GEARING.

Specification of Letters Patent.

Patented March 12, 1907.

Application filed May 26,1906. Serial No. 318,862.

To aZZ whom it may concern.-

Be it known that I, ALPHONSE GERBER, a citizen of the United States, residing in 1at erson, county of Passaic, and State ofNew Jersey, have invented certain new and useful Im rovements in Gearing; and I do hereby else are the following to be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specifica tion.

My invention relates to hydro-extractors; and it consists in certain improvements in the means for driving the basket of such machines, whereby the speed may be controlled ic ruickly and readily and may be changed om materiallyhigh to materially low, according to the use to which the machine is put-41. e., simply as a hydro-extractor or also as an apparatus for washing or weighting silk, under which latter circumstance the basket should rotate slowly in order that the treating liquid will be distributed uniformly through the material. Incidentally said improvements effect an avoidance of undue lost motion between elements in the driving-train, the reduction of vibration to the minimum. and several other advantages, some of which will be made apparent in the following description on a view to the accompanying drawings, wherein Figure 1 is a view in front elevation showing the machine artly broken away. Fig. 2 is a view looking rom the right of the machine, as shown in Fig. 1, certain parts appearing in section and others being broken away. Fig. 3 is a rear vew of the basket-driving means, and Figs. 4 and 5 illustrate details.

In the drawings, a is a circular plate of slightly convex form having a vertical circumferential flange b and a discharge-outlet 45 c. d is a central bearing mounted on said circular plate. e is a cylindrical. shell which seats on the circular plate, fitting within the flange b. The foregoing parts are supported by four legs f, which rest on an annular baseate 9.

p h is the bed which may be formed in any suitable manner and supports the base-plate whereby it affords a strong substantial support for the parts it is intended to carry.

On the base-plate g rests the ends of the arms of a spider i, which carries centrally a stepbearing j. The armsi are not horizontal but inclined toward the body or bearing portion j of the spider, so that said bearing portion is relatively depressed, standing partly below the top surface of the base-plate g. In the step-bearing is journaled a shaft k, which projects up through the bearing d and carrice the basket Z, whose cylindrical wall is perforated in the usual manner.

On the shaft is is splined a friction-wheel m. This friction-wheel rests on a two-part collar at, whose sections are held together removably by bolts 0. This collar has diametrically opposite trunnions p, which are received by the ends of a fork q, in turn pivoted in the two members of a stand 1", itself pivoted in one of the arms of the spider. The fork g has its free end grooved, as at s, on the side, and in this groove fits one end of a handle t, which is bolted to the fork. Said handle carries a block a, penetrated by a rod v, pivoted in a bracket w on the base-plate g, and by manipulating a hand-screw x, mounted in said block and adapted to take against the rod the handle t may be set at any position. In the foregoing means is provided for moving the splined friction-Wheel m V61: tically on the shaft 7:.

The bed h is extended at the rear, as shown best in Fig. 2, and on such extension y thereof rests a plate 2, which is secured thereto, as by bolts 1. On this plate rests an engine 2 of the reciprocating type, whose frame 3 comprises a cylindrical guide 4 for its crosshead 5. This guide is split, as at 6, and provided with bolts 7 at its outer end, so that lost motion occurring between the crosshead and the cylindrical portion 4 may be taken up from time to time. The frame of the engine also comprises a horizontal bearing 8, in which and a bearing 9, carried by a cross-piece 10, connecting two of the legs f, is journaled a horizontal shaft 11. This shaft carries at its inner end a face-plate 12, against which the friction-wheel 'm impinges.

The piston-rod 13 is connected with a crank 14 on a crank-disk 15 on the shaft 11 by the connecting-rod 16, said crank being formed with an extension 18, to whose crank-pin 19, disposed eccentrically of the shaft 11, the link-motion 20 is connected.

The crank-plate 15 and a collar 21 on shaft 11 confine it against movement longitudinally in the bearing 8. In order to insure at all times a positive engagement between the friction-wheel and face-plate, the engine is arranged to have some slight movement on its base 2 toward shaft lc, a lever 22 extending from a shaft 24, journaled in brackets 25, and also carrying earns 26, engaging lugs 27 on the frame of the engine, being provided for this purpose. This lever may be secured where adjusted by a means similar to that shown in Fig. 4 for securing lever 9 28 being a block carried by the lever and penetrated by a rod 29, pivoted in plate 2, and 30 a hand-screw mounted in the block for clamping the block at any position on the rod. Bolts 31 are provided for securing the engine to its base 2, but they are not adjusted so tightly that the movement of the engine toward the shaft k under the action of the lever 22, as above described, is prevented. By this means under all conditions the friction-wheel and face-plate are kept in constant contact with each other, so that lost motion between them is reduced to the minimum. A weight is hung on the lever, the action of which is to cause the parts m and 12 to adjust themselves nicely to each other before the securing means shown in Fig. 5 is made use of to fix them where so adjusted.

The driving arrangement herein described makes it possible to impel the basket not only at materially high and materially low speeds but at any speed between these according to the position of the friction-wheel m relatively to the center of the face-plate 12. On account of the spider being depressed in its bearing portion 3' the frictionwheel may be, moreover, moved down below the center of the plate 11 while the latter is rotating, so as to cause said face-plate to act as a brake to stop the basket.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of the frame, a driven shaft journaled therein, a driving-shaft, power-transmitting devices carried the one by one shaft and the other by the other shaft, the one on the driven sshaft being splined thereon, means for shifting said lastnamed device lengthwise of its shaft comprising a lever and a link pivotally connected with the frame and affording a fulcrum for the lever, and means for securing said lever in any position to which it is movable on its fulcrum, substantially as described.
